Dogs vomit and have no energy

There are many causes of vomiting and diarrhoea in dogs. Common ones include viral diseases such as distemper, canine microcephaly and canine coronavirus; parasitic diseases such as leptospirosis and roundworms; and medical factors such as liver and kidney diseases. When vomiting and diarrhoea increase in frequency, this can lead to dehydration and electrolyte disturbances in the sick dog, which can cause symptoms such as mental depression. Fluid therapy and supportive therapy are generally recommended for this condition, along with laboratory tests to determine the cause as soon as possible.
